{"version":"1.0","type":"rich","title":"Fork of World Countries Tree2","description":"This visualization presents a hierarchical tree of world countries, organized by continent and subregion, using a static SVG layout. The code constructs the tree with `d3.tree` and `d3.hierarchy` from a nested JSON data source, rendering parent-child links with `linkHorizontal`. A zoom behavior enables pan and zoom interaction on the entire tree, while labels are styled with the Playfair Display font. The visualization demonstrates a straightforward approach to displaying geographical groupings without additional data encoding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e5a8fda1e58349128fba96d2afad8dc4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
